To all whom it may concern:

Beit known that I, WORTHINGTON SCRAN- TON, of New1 Haven,in the county of New Haven and State ot Connecticut, have invented new Improvements in Gong-Bells; and I do hereby declare the following, when taken in connection withthe accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part ot' this'specitcation, and represent, in-

Figure l, a front view of the post and mechanism with the bell removed; Figs. 2 and 3, the same views with -portions removed and showingthe parts as in operation; Fig. 4, front View ot' the base-plate`5'Fig. 5, perspective view ot' the slide from the under side; Fig. 6,

perspective view of the hammer-lever; Fig. 7, perspective view of the trip detached i Figs. 8, 9,-10, a`nd ll, detached sectional views.

This invention relates to an improvement in that class of bells commonly ca lled gongbells]7 and such as are applied sometimes di- -rectly to a door to be operated by a lever upon the outside, and sometimes at a distance to be operated through a ,line of wire,`the object 'of the invention being to simplify the usual construction, whereby all the partsmay be cast complete, requiring only the subsequent tumbling operation, thereby avoiding the usual mechanical labor in the completion ofthe bell; and the invention consists in the construction, as hereinafter described, and particularly recited in the claims. Y

A represents the base or plate, which is titted with ears B or other devices for securing the bell in place. 1t is .of usual circular shape, or may be of any other desirable outline, and is provided with the usual center post, C, to which the bell is attached. n

`Dis the slide, having alongitudinal opening, E, through it, so that it may-set over the center post and be moved longitudinally-that is,

dametrcally--either by pull or lever itted at one end with an eye, a, for the attachment of the wire, and at the other end with an opening, b, for the lever, either with the o'ne or both, or maybe otherwise arranged for connection with the pull.

On the plate A is a rib, d, (see Figs. 4 and 11,) running parallel' with the diametricalline hookshaped lug, f, (see Fig. 4,) which extends over the edge of the slide when in place, as seen in Fig. 1. This hook-shaped lug is made in casting by I'orming an opening, F, below it, as seen in Figs; 3, 4, and l1. On the other side of the center-post two lugs, h h, similar to the lugs f are arranged, so as to hook the one over one side of the plate and the other over the other, as seen in Fig. l, the lugs h l1.v and f serving to hold thel slide in place upon its guide. The lugs It IL are also formed in casting by leaving an opening, H, through the plate below, as seen in Fig.v 10. In order to introduce the slidebeneath these hook-shaped lugs and upon its guide d, the slide is constructed with a notch, @,npon its two sides and opposite each other, and so that the slide being introduced beneath the lugf the notches it' will pass down over the lugs h, the slide at this time being in the position seen in broken lines, Fig. 4. Then the slide is moved backward to bring it beneath the respective lugs, as seen in Fig. l, and in which position it will slide freely back and forth, held in its position by the said lugs.

I is the hammer-lever, arrangedA upon a stud,

k, caston the plate A, the lever cast with an opening, l, corresponding to said stud, as seen in Fig. 6. To prevent its accidental slipping from said stud, the 'hub of the lever is cast withya notch, m, at one side to set down over' bell-hammer? is attached to one end of the lever I, so as to turn upon the stud or pivot k. A two-armed' wire spring is arranged upon a stud, r, one arm, s, bearing upon the hammerlever, the other arm, t, bearing upon a lug,u, on the slide, the tendency of' said spring being IOO to force the slide in one direction and the hamof the hammer-lever that the recess L in the mer in the opposite direction or into their normal position, but yield for the operation of the parts.

0n the underside ofthe slide D is a recess, L, (see Figs. 2, 3, and 5,) into which the trip R is placed. This trip, as seen in perspective, Fig. 7, is constructed with a groove, w, upon its under side, so as to rest and ride upon the guide d, and is shorter than the recess L, as seen in Figs. 2 and 3, so as to have a certain amount of freedom within the spaces L of the slide. On one side ot' this trip a projection, T, is made, extending toward thehammer-lever l, and is preferably inclined upon its two sides to an angle of nearly forty-live degrees, the end of the bell-hammer being correspondingly inclined, so as to make a similar point, V, projecting toward the slide when in a state of rest, as seen in Fig. l. This trip lies in rear of the end of the lever L, and in contact, or nearly so, with the rear end of the recess L in the slide. Hence when the slide is moved, as in Fig. 2, the projecting part T of the trip forces the corresponding end ofthe lever away from it, as shown in that figure, until the one can escape from the other, then the force of the spring throws the lever back to its place of rest, and in so doing the correspondinglyinclined surfaces of the lever and trip force the trip` forward in the recess, as seen in Fig. 3. This leaves the hammer free for a quick return or stroke-that is, it cannot be let down easily, but must ly back with the full force of the spring, because the trip is forced by that spring out of the way of the lever. On the return from the position seen in Fig. 3 to that `in Fig. 1,the trip acts in the same manner but upon the opposite side of the point V of the lever. Fig. 8 showsalongitudinal section through the slide and trip. It is for freedom slide is made longer than the trip, and the trip made independent or detached from the slide. A good result, however, may be pro duced with the trip made a permanent part of the slide, or the trip may be hinged to the slide, so as to operate upon the bell in one direction and pass overin the opposite direction, an arrangement of trip well known.

By this construction all the parts ofthe bell except the spring are readily made in the process of casting, and require no other mechanical labor to lit them for assembling than that given by the tumbling or cleaning operation. it is not liable to get out of order, and is as cheap as it is simple.

.The construction and arrangement ot' the slide may be applied to other hammer mechanism. Hence I do not wish to be understood as limiting the invention to the construction and combination of all the parts as hercinbebefore described; but

What I do claim is- In a gong-bell in which the hammer is operated by a slide moving longitudinally or in the same plane with the base or plate, the said plate constructed with hook-shaped lugs, and the slide with notches in its edges to set over said lugs and permit the edges ot' the said slide to come beneath the said lugs, and be held in place by said lugs, the said slide also constructed with a recess, L, combined with a trip, R, arranged in said recess, and less in length than the said recess, and a hammerlever, one arm of which is operated by said trip, moved by said slide, substantially as described.
